This has worked well for me, with no detectable audio lag. I've only used it on plane rides, and it connected easily and worked well. I haven't had a flight longer than 3 hours since I got this, but I can say the battery lasted for the entire travel time. An on-the-go tip for you to ensure you always know how to connect it: type some quick directions in your Notes app (or other memo-keeping app) on your phone. That way you'll still be able to use it if you forget how it works and don't have the instruction booklet.

This lightweight device allowed me to wireless send audio from a Quest3 or MIDI Synthesizer analog output to a receiving bluetooth device on my PC without groundline noise as typical for wired connections. Pairing was achieved quickly.

Ich bin begeistert von dem Bluetooth 5.3-Sender, der sich als wahrer Alleskönner entpuppt hat! Dieses Gadget hat meinen TV, der leider kein eingebautes Bluetooth unterstützt, in ein modernes Entertainment-System verwandelt. Jetzt kann ich beim Sport Filme und Serien genießen, ohne jemanden zu stören, denn die Verbindung zu meinen Kopfhörern klappt einwandfrei.Die Einrichtung des Transmitters war kinderleicht. Einfach die Kabel verbinden, einschalten, und schon war das Gerät einsatzbereit. Die intuitive Touch-Steuerung hat die Bedienung zusätzlich vereinfacht, was ich besonders praktisch finde. Der Wechsel zwischen Heiß- und Kaltbetrieb funktioniert reibungslos, was ihn vielseitig einsetzbar macht.Der Klang ist ausgezeichnet, und die Synchronität zwischen Bild und Ton ist so gut, dass selbst actionreiche Szenen ohne störende Verzögerungen übertragen werden. Dank des eingebauten Akkus mit einer beeindruckenden Laufzeit von bis zu 30 Stunden muss ich mir keine Sorgen machen, mitten im Film ohne Ton dazustehen.Ein weiterer Pluspunkt ist, dass der Adapter automatisch in den Standby-Modus wechselt, wenn der TV ausgeschaltet wird, und sich nahtlos wieder verbindet, sobald der TV eingeschaltet wird. Das spart Energie und erhöht den Komfort.Kurz gesagt, dieser Bluetooth-Sender hat mein Zuhause technologisch aufgewertet und das zu einem erschwinglichen Preis. Er ist die perfekte Lösung für alle, die ihre älteren Geräte ohne Bluetooth-Funktion nachrüsten möchten. Klare fünf Sterne von mir für dieses tolle Produkt! 🌟👍

Short, Sweet, and Simple Review. The product performs well overall. There's a minor audio lag occasionally, depending on the device it's connected to, and some intermittent static noise, but these issues are not significant enough to be a dealbreaker. The pairing process is surprisingly easy, and the battery life is impressive, lasting the full use between 4 to 9 hours at a time on a full charge without any problems and still having additional battery life leftover. While I'm uncertain about repurchasing this item and might explore other options, it's definitely worth considering for its price point if you're in the market for such a product.

I wanted to use this to transmit sound from an old CD player that does not have bluetooth to a set of earbuds. I connected the device to the headphone jack in my old CD player and then followed the instructions to pair the device with the earbuds, but no matter which set of earbuds I tried, I could not get this device to pair with them. I am able to pair the earbuds easily with other devices, like my computer and my iphone, so I know they are not the problem. This is so frustrating and disappointing. I will continue to try and modify my review if it turns out to be user error or a problem with the CD player audio jack or something else unrelated to this product.

Der Bluetooth 5.3-Sender ist ein vielseitiger Audio-Adapter, der sich durch einfache Handhabung und gute Übertragungsqualität auszeichnet. Dank der neuesten Bluetooth-Technologie 5.3 bietet er eine stabile Verbindung und eine größere Reichweite. Die Installation ist unkompliziert und funktioniert reibungslos mit verschiedenen Geräten wie Fernsehern, Kopfhörern und Lautsprechern. Die Klangqualität ist klar und verzögerungsfrei, was besonders bei der Nutzung mit Kopfhörern oder Heimkinosystemen positiv auffällt. Ein kleiner Nachteil ist, dass die Bedienungsanleitung etwas ausführlicher sein könnte, insbesondere für technisch weniger versierte Nutzer. Insgesamt jedoch ein empfehlenswertes Gerät für alle, die ihre Audioquellen kabellos verbinden möchten.

The Xbox Series X and the PS5 both have some annoying things like trying to force you to use wired headphones when they could have easily allowed Bluetooth earbuds like the Switch eventually did. So that's where this product comes in. You recharge it, then you plug it into the game controller and turn it to transmitter mode and turn on your Bluetooth earbuds and they should automatically sync assuming that your Bluetooth earbuds aren't registered with another device that is ready to connect to them. Overall it added very little weight and basically no discomfort for me when playing games. If you have a tendency to move your controller around a lot, you might have issues with moving this all over if you don't tape it down or something. It's a little smaller than a typical cup coaster. I only had one incident where sound became distorted and it was the earbud against my pillow and this device across from my body causing a lot of interference. 99.9% of the time the came in fast and cleanly. I also used the device for a few days before needing to charge it. Probably best to charge while sleeping. I game for up to 8 hours. So a few days of battery was pretty good.Overall I strongly recommend as I use this almost daily, especially at night when my wife is asleep.

This device has a couple of nice features. One of them is that it supports either receive mode, to send audio from a bluetooth player to an output device, or transmit mode, where you can hook up a non-bluetooth player and send audio to a bluetooth speaker. I've only ever used the receive mode, so not sure exactly how the transmit mode works, but it supports both. The other nice feature is the built-in battery, so you can charge it up but then continue to use it when it is unplugged.That said, it has a couple of annoying things about it, particularly in a car application:* While the battery is nice, it means that, most bluetooth players (Phones) stop playing when the bluetooth device disconnects, which is nice when you get somewhere and turn off your car - the audio pauses. With the battery, this doesn't happen, so the audio keeps on playing despite the fact that no speakers are connected.* The volume level is generally quite low - I have to have my phone up pretty high, and then the car stereo that I'm connected to also up pretty high, to hear it well - which causes the overall quality to be not great.It's an inexpensive device, and versatile with the dual-mode, but, again, not ideal for a car setting.

The main thing to say about this is that it arrives in very simple, plain, straightforward packaging. It absolutely works and does the job that it's meant to, but for the love of god don't lose the instruction booklet that comes with it. It is just quirky enough to be a device that you don't use often enough to be able to remember exactly what the pairing protocol is..All in all, I'm actually super happy with it; mainly because it WORKS, and is in a nice small form factor. I'm pretty happy with the playtime I get out of it too.

This is a great way to listen to to the airline monitor audio without using a wired connection. I have a bluetooth earbud that I use for my phone and this is great way to use my existing earbud vs having to carry another set of earbuds for hearing the audio from the airline monitor.

This very handy bluetooth accessory is an excellent solution for adding bluetooth capabilities to devices that do not have that functionality built in. I wanted to be able to hear the audio on a television in a noisy room, and these were perfect for making that work. Add this handy device and plug it into the audio output from the television. Now I can use my bluetooth headset to clearly hear the audio despite all the background noise in the room. Dialog is completely clear to understand and worked smoothly on the first try.
